It is a legal responsibility to do so and those who don’t fill in the census by 1 May, may face prosecution, which could lead to a criminal record and a fine.

National Records of Scotland Chief Executive Paul Lowe said: “Taking part in the census is a legal responsibility. The census provides vital information required to invest in and run the services we all rely on.

“It’s not just the public sector; charities and businesses use census data to help them make decisions. By answering questions about yourself, your home and your household you are having your say on what services are needed in your community.

“I’d like to thank everyone who has filled in their census. For anyone who has yet to complete it, help and support is available on the website census.gov.scot or via a free helpline on 0800 030 8308.

“Guidance is available for every question in English and 16 other languages on the website. An interpretation service covering most languages can be accessed by calling 0800 030 8333. You can also request copies of the guidance in Braille, large print or on audio CD or USB. There are guidance videos in British Sign Language on the key pages of the website and a video relay service offered by contactscotland-bsl.org can be used by BSL users to access advice from the helpline.”

Anyone who can’t complete the census on their own can ask someone they trust over 16 years old for help.

Reminder letters have been sent to every household in the country who is yet to complete the census and field staff are visiting addresses that haven’t completed their return to offer advice and support.
